If you want reliable Wifi at home, get yourself Ubiquity access points and throw away TP-Link. The issue is not the protocol. After many years of unplugging and plugging back in my TP-link router I know that they are cursed.

Ubiquity stuff was giving me constant buffer bloat issues and it was a pain to do basic configuration for. Just too many options.
TP-LInk generally works just fine as long as the WiFi channel is clear.
